Yamaha IPOD Docks - the YDS11 or YDS11SL

Hi

Does anyone know if the YDS11 is the same as the YDS11SL? Looking at Amazon, the only difference seems to be 20 quid, but does anyone know if they're the same?

See:

I want to connect it to my RXV-1800 receiver and 3rd gen Nano but the Yamaha website still refers to the YDS10 which is the older model. I received a 2008 printed brochure from Yamaha in the post today which highlights the YDS11 as being compatible but I can't find a mention anywhere of the YDS11SL.

Does the SL maybe just mean its the silver colour they're selling....or am I having a silvery blonde moment?

Any thoughts appreciated.
